Fairly catastrophic failure here - the migration failed on my online VPS: grub-install failure for /dev/vda4 (full log). Now, when I go to try to fix the issue, none of my admin users have sudo permissions anymore, and I cannot log in with root (neither via SSH or directly using the VNC function from my VPS provider). Iâm a bit concerned here as this is a large media hosting VPS for which I cannot afford a backup. Any help appreciated!
Note: the log is from my second attempt to migrate - the migration failed earlier initially with the same error.
Update:
- Fixed the sudo issue by resetting the root password and adding admin users to the sudo group.
- Ran
sudo DEBIAN_FRONTEND=dialog dpkg --configure grub-pcper log: received a scary warning saying that GRUB had failed to install on /dev/vda4 and asked whether I would like to continue knowing that my machine may not boot. I selectedyesas I was fairly certain that vda4 wasnât my boot device, and the logs had indicated that GRUB had installed succesfully to /dev/vda2, which is my boot device according to the output ofcat /etc/fstab/. - âŠand it survived a reboot.
